Question 327549
The distance a car travel on a certain amount of fuel varies inversely with its speed. If a car traveling 50 mph con travel 300 miles on 10 gallons of fuel, how far could the car travel on10 gallons of fuel at 60 mph?
-------------
distance = k*fuel/rate
---
Find "k" using d=300 when rate = 50 mph and fuel = 10 gals
300 = k*10/50
---
k = 1500
----
Equation for this situation:
d = 1500*f/r
-------------------------  
How far could the car travel on 10 gallons of fuel at 60 mph?
-------------
distance = 1500*10/60 = (1/4)(1000) = 250 miles
